To all whom it may concern;

Be it known that we, ALBERT DILTHEY, residing at Cortland, and MELVIN F.ROCK, residing at Homer, in the county of Cortland and State of NewYork, citizens of the United States, have invented certain new anduseful Improvements in Door-Holders; and we do hereby declare thefollowing to be a full,clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention relates t0 a door holder or stop; and the primary objectof the same is .to

produce a device of this class embodying ai shank or slide-bolt with alower holding-head having simple and effective means in connectiontherewith to draw it out of contact or engagement with a floor-surfaceor sill and sensitively-coacting locking elements whereby the said shankor bolt may be held either in a locking or stopping position withsufficient positiveness to resist accidental disengagement or beretracted and likewise held against loose movement when elevated.

With these and other objects and advantages in view the inventionconsists in the construction and arrangement of the several parts, whichwill be more fully hereinafter described and claimed.

In the drawings, Figure lis arperspective view of the improved holder orstop shown applied and the parts arranged to hold a door inpartially-open position. Fig. 2 is a transverse vertical section takenin the plane of the line 2 2, Fig. 1. Fig. 3 is a front elevation of aportion of the improved device.

Figs. 4 and 5 are detail plan views of parts'of the device. Y

Similar numerals of reference are employed to indicate correspondingparts in the several views.

In applying the improved holder or stop it is secured to the lowerportion of a door adjacent to the free edge thereof, and said de- Viceembodies a supporting-plate 1 of suitable ornamental contour and havingan upper irregular heart-shaped member 2 integrally formed therewith.The support 1 is secured to the door by suitable fastenings, which willbe hereinafter set forth, and it is Fig. 3av is an edge elevation of apart of the device.,

preferred in the construction of the said support and member 2 that theybe cast of suitl able metal and afterward dressed as desired.

The member 2 comprises opposite segmental rims 3 and 4, the rim 3 beingconsiderably longer than the rim 4, and between the rims anda centralbar 5 the member 2 is formed with openings 6 and 7 to lighten thestructure and clearly define the bar. From the upper end of the bar 5the rims 3 and 4 emanate and extend downwardly adjacent to oppositelateral projections 8 and 9,1'espectively, the said projections being atdifferent elevations or the projection 9 higher than the projection 8.The lower terminals of the rims 3 and 4 are not connected to theprojections 8 and 9 and are free to move, both rims being graduallyprojected outwardly at anincline from their upper extremities towardtheir lower terminals, as clearly shown by Fig. 3a, and have an inherentresiliency to cause them to always resume an outward normal positionwhen free to do so. The outer faces of the rims 3 and 4 are formed witha series of transversely-extending teeth 10, which are in the nature ofregularly-arranged corrugations. The bar 5 has a'centralvertically-disposed slot 11, and in one side wall of this slotratchet-teeth 12 are out or otherwise formed. These ratchetteeth are ofshallow depth, and coacting therewith isan upwardly-extending arm 13,having shallow teeth 14 and forming a part of a verticallyreciprocatingshank or bolt 15, which moves through and is held in operative positionby a box 16, applied over the lower portion of the support and held inconnection with the latter by a plurality of screws or analogous devices17 passed therethrough. When the arm 13 is pressed slightly laterally inone direction, the teeth therein are caused to engage the ratchet-teeth12, and when the said arm is moved slightly in the opposite directionthe teeth 14 are disengaged from the teeth 12. The screws 17' alsoextend through the support 1 and serve as a securing means for thelatter, and to maintain the shank or bolt l5 in true operating positionand prevent rotation thereof the lower extremity is formed angular incross-section, as at 18, to engage and freely slide throughcorrespondinglyshaped openings 19 in the opposite ends of IOO the box16, as clearly shown by Fig. 5. The slot 11 in the bar 5 is continueddownwardly through the support 1, and the part of the shank or boltabove the angular extremity 18, as well as the arm 13, is located andmoves in the slot 11 and the continuation of the latter in the saidsupport. As shown by Fig. 2, the lower angular extremity 18 is projectedoutwardly and the point of juncture of said extremity with the part ofthe shank or bolt above the same, in view of the outward projection ofsaid extremity, is shouldered, as at 19, and downwardly inclined tocontact with a correspondingly-inclined lower end wall of the slot inthe support 1, forming a continuation of the slot 1l, so as to limit thedownward projection of the shank or bolt. On the lower end of the shankor bolt is a head 20, having a lower bufing or yielding covering 21, thesaid head being adapted to be moved downwardly into a socket 22, locatedat a suitable point in the sill, or to be brought in contact with thefloor-surface, as shown by Fig. 1, and in the latter contact the buftingor yielding covering 2l will serve to establish a certain amount ofadhesion or resist slipping action of the said head. The shank or bolt15 at the upper extremity and adjacent to the arm 13 is also formed withan outwardly-extending eurved projection 23, which is of approximatelycircular form, and with this projection the operating device is held incontinual contact. The upper terminal of the arm 13 is also providedwith a forwardly-projecting pin or stud 24, which continually engagesthe operating device, and by a certain movement of the latter the shankor bolt 15 is elevated. .j

The bar 5 above the upper terminal of the slot 11 has a tubular hub orsleeve 25 outstanding therefrom a suitable distance, and thereover isrotatably fitted the operating member 26, which is held in place inrelation to the hub or sleeve by a washer or disk 27 and a screw 28. Theoperating member 26 comprises a laterally-extending arm 27, having alongitudinally-disposed rib 28 near its outer end to engage the teeth orcorrugations of the rim 4, the said arm terminating beyond the rim 4into an outstanding grip or knob 29. The operating device 26 alsocomprises a cam-arm 30 with a depending curved cam member 31, having itslower edge in continual engagement with the upper portion of theprojection 23 on the upper terminal of the shank or bolt 15. The inneror rear face of the cam member 31 is formed with a correspondinglyshaped groove 32, as clearly shown by Fig. 4, and into said groove thestud or projection 24 extends, and by this means the shank or bolt 15may be positively raised and lowered when the operating device 26 isoscillated or moved on its fulcrum in reverse directions. The cam-arm 30also includes an outwardly-projecting extremity 33, having a substantiallongitudinally-extending rib 34, which is held in continual engagementwith the teeth of the rim 3, and said extremity 33 terminates inan outstanding grip or knob 35. Owing to the eccentric mounting of theoperating member 26,as heretofore set forth,a downward depression of theextremity 33 thereof will cause the arm 13 to move toward theratchetteeth 12 su Hiciently to cause both sets of ratchet-teeth 12 and14 to become engaged, and an opposite or upward movement of the saidextremity will press the arm 13 in an opposite direction and disengagethe ratchetteeth 12 and 14.

It will be seen that the operating device 26 is eccentrically mounted inthe member 2 to make the cam-arm 30 effective in elevating anddepressing the shank or bolt 15. By having the lower terminals of therims 3 and 4 free and said rims gradually inclined outwardly from theirupper extremities the rims are held in continual operativeengagment withthe ribs 28a and 34, carried by the opposite portions of the operatingdevice `26,and a binding action will ensue sufficient to maintain theadjustment desired and a retention of the opposite portions of theoperating device in relation to the teeth of the rims to preserve thedesired position of the shank or bolt 15 in either its elevated ordepressed arrangement or disposition. As an auxiliary in effectivelyholding the box 16 against movement the opposite sides thereof areprovided with spaced pairs of lugs 36 to iit in corresponding slots 37in the support 1, these lugs relieving the screws 17 of a large portionof the strain brought to bear on the said box.

From the foregoing description the operation of the improved device willbe readily understood, and it will be seen that it can be used either asa lock for holding the door closed or as a means for stopping orchecking a door it may be desired to hold open a certain distance. It isalso proposed to suitably ornament or plate the several parts and,furthermore,to vary the proportions,dimensions, and minor details withinthe scope of the invention.

Having thus fully described the invention, what is claimed as new is- 1.In a device of the class set forth, the combination of a support havingan upper member with opposite toothed rims, the said rims being inclinedoutwardly from their upper extremities and having their lower terminalsfree, an operating device mounted to oscillate in relation to said rimsand having catch devices to engage the teeth of the latter, and a boltconnected to the said operating device.
